In the show at least, Kitt was more or less indestructible (the only time Kitt got wrecked so badly that it needed a mid-season upgrade was when Michael Knight thought it was a good idea to take on a SWAT tank which ended up going exactly as well as one would've expected it to) so its not unlikely that Michael probably could've done a circle inside the apartment then launched Kitt back out the way they came without too much trouble (and its not like anybody cares about the apartment anymore). Of course, with only one Turbo Boost per episode, the question really becomes how much longer did that episode have left to go on for?
